  • Add cucim.is_available() method

Users can query if a specific module is available or not.

For example, if cucim.clara module which requires C shared library is not available:

>>> import cucim
>>> cucim.is_available()
False
>>> cucim.is_available("skimage")
True
>>> cucim.is_available("core")
True
>>> cucim.is_available("clara")
False

Thanks Gigon! 😄

Looks good. Had one question above

python/cucim/src/cucim/__init__.py
except ImportError:
from ._version import get_versions
__version__ = get_versions()['version']
del get_versions
del _version


def is_available(module_name: str = "") -> bool:

Should we add a test for this function?

@jakirkham Conda-related CI/CD failure happens again here.

Are we sure it is Conda related? Looks like it happens part way through the build. Please see snippet below:

15:35:06 [ 77%] Building CXX object CMakeFiles/cucim.dir/pybind11/filesystem/cufile_py.cpp.o

Would recommend increasing verbosity from cmake & make to get a better idea on why the build dies there

#106

https://gpuci.gpuopenanalytics.com/job/rapidsai/job/gpuci/job/cucim/job/prb/job/cucim-cpu-python-build/CUDA=11.2,PYTHON=3.7/61/console

Looks like the failure is because #106 is merged.

Will rebase this on top of the latest change.
